MA signal calibrator ADT760 series

pressurefor pressure gaugesfor pressure sensors

Overview
The Additel ADT760A is a high-performance automatic portable pressure calibrator designed for field accuracy and mobility. Weighing under 1.8 kg, it integrates an electric pump, an internal controller and interchangeable pressure sensor modules. The ADT760A features a capacitive touchscreen and four measurement channels (internal pressure, two external pressure channels and one electrical channel). The ADT760S is the version without electrical measurement/sourcing, suited for gauge calibration and pressure measurement with centralized display.

Main features

• Automatic generation and control of pressure up to 25 bar (375 psig).
• Fully automatic pressure calibrator with built-in pump (replaces manual pumps).
• Three range configurations: LLP (low pressure), D (differential/relative), MA (vacuum to 25 bar.g).
• Accuracy up to 0.01% FS depending on model/module.
• Interchangeable internal ADT155 pressure modules for multiple ranges, including very low pressure.
• HART communication option and data logging (DL models for ADT760A).
• Non‑electrical version available: ADT760S.
• Mass < 1.8 kg for handheld use and easy transport.
• Communications: USB, Wi‑Fi and Bluetooth.
• Data logging and task management features (DL option on ADT760A).
• Contamination prevention system (CPS option).
• Support for external pressure modules (two external channels).
